High Wind Bio-Mass Cap

ABSTRACT

The use of the High Wind Bio-Mass Cap helps with the ventilation of corn or pellet stoves, inserts, or fireplaces in a high or low wind area. 
     You attach a High Wind Bio-Mass Cap to the end of a pellet or corn vent pipe where it terminates at a manufactures specified location. You may attach this cap as low as 12″ to the ground and it can face either horizontal or vertical. The cap increases the flow dynamic by creating a low pressure area at the exit of the vent pipe. By lowering the pressure at the end of the pellet or corn pipe it lowers the pressure on the ventilation motors of any of the units, which will possibly extend the life of the stove/units ventilation motor. Being only 12″ from the ground and facing horizontal this is the only cap that will keep a breeze from creating a possible back draft.

BACKGROUND OF THE INVENTION

The present invention relates to a product that you attach to the end ofa pellet or corn appliance exhaust pipe. As air passes by the cap itlowers the pressure of the exhaust released from a corn or pellet stoveor insert and pulls it from the flue from which it is attached. Thisidea came from having current caps which are placed on the end of apellet or corn pipe just for a cover but do not help the draft. They donot allow you to put your stove on a very windy side of the housebecause the wind would flow back into all current caps. Placing the HighWind Bio-Mass Cap on the end of the pellet or corn vent would allow youto vent your stove out any side of a house “windy or not” and would helpvent the stoves even on a still side of a house. This is a stainlesssteel cap made for a pellet or corn appliance. Corn and Pellet stoveshave a 3″-4″ chimney pipe that emerges from the outside of a wall orroof. After the chimney pipe comes out far enough to match fire codesyou place High Wind Bio-Mass Cap on the end. Using the design shown with6 bars in different directions it allows the stoves to vent as well anddraw exhaust much stronger than any existing corn or pellet capcurrently on the market. With 3 bars facing different directions on theinside and 3 bars facing different directions on the outside it makesthe slightest breeze that pass work like a vacuum. Circulating airaround the end of the cap lowers the pressure of any gasses on theinside helping to draw any units exhaust. This is called the Venturieffect and came about back in the mid 1700's. With six bars the draw isstrong enough it allows this cap to sit as low as 12” above the groundand face horizontally as well as vertically.

SUMMARY OF THE INVENTION

An object of the present invention is to help draft a pellet or cornstove in windy conditions. It uses the Venturi effect to draw emissionsgiven off from a unit to the end of the flue.

Another objective of this present invention is to allow corn and pelletburners to draft easier with less power demand.

DETAILED DESCRIPTION OF THE DRAWINGS

A venting cap apparatus in accordance with the preferred embodiment ofthe present invention is described with reference to FIGS. 1 to 6

FIGS. 1, 2 show the cap in a horizontal position so you can see itsshape in a 2.4^(th) shrunk view. FIG. 1 as seen in 1A and 1B, is wherethe spot welds which hold the bars on to the 3-4″ round base.

FIG. 2 allows you to see how the cap has a flattened oval shaped top.The top of this cap will be in an oval shape approximately 3 times widerthan it is tall making the top approximately 6″ wide. 2A shows theexterior ring which surrounds the smaller interior ring seen at 2B. Both2A and 2B are connected to 2C which is the base. 2C is the part of thecap which fits on to an existing pellet or corn exhaust pipe.

FIG. 3 allows you to see a slanted version from the top. In FIG. 3 youcan see how the top is wider than it is tall. This is a hand madeversion so there are screws shown at 3A this is the point where a spotweld will be placed to hold the top together.

FIG. 4 allows you to see the cap from a top down view or if sittinghorizontally. You see the 6 intersecting bands on the outer surround 4Aand the 6 intersecting interior bands seen inside the exterior surroundat 4B

FIG. 5 is an interior view of a High Wind Bio-Mass Cap. And shows theend which is to be attached to a pellet or corn vent 5A shows how itattaches to a pellet or corn vent by screwing on for security. Where thescrews are seen in 5B is where the spot welds will be in a factoryproduced cap.

FIG. 6 shows the basic shape from bottom up. This is the High WindBio-Mass cap which is attached to a pellet or corn vent to help andincrease venting abilities.

I. We claim to have invented this cap made for pellet or corn ventingpipes II. Stated in I this cap fits on the end of pellet or corn pipesfor ventilation purposes. III. When attached on the outside of a pipefacing either vertical or horizontal it helps a pellet or corn unit ventby lowering the pressure inside the pipe. IV. Like stated in III. Whenfacing horizontal the option of a rain cover is offered.
